Paper Abstract

Interference fringe localization in double-exposure speckle photography is discussed. It is shown that fringe visibility distribution is defined by the Van-Cittert-Zernike theorem and that fringe contrast has an oscillating nature especially expressible for complicated and periodical apertures of spatial filtering optical or observation system. Interference fringe localization areas and their visibility distribution are discussed for simple object displacements--lateral and longitudinal shear, inclination and in-plane rotation. Fringe visibility oscillation is demonstrated for ring and double circular apertures of a spatial filtering optical system.
